DISMOUNTABLE ASSEMBLED SUPPORT AND METHOD FOR TENSION OF FLEXIBLE MEMBER OF DISMOUNTABLE ASSEMBLED SUPPORT Russian patent published in 1994 - IPC

FIELD: construction of temporary shield guards. SUBSTANCE: support has vertical post and, at least, two horizontal lugs whose longitudinal axes lie in same plane. Post and lugs are made of similar in shape inserts interconnected by flanges. Flexible member (rope) passes inside sections of lugs and post and ensures combining of sections when tensioned. One ends of flexible members are attached to joint body by means of studs, and the other ends are secured to center of covers of post and lugs. Flexible members are tensioned by structure assembler with force which is maximum close to design value. For this purpose, tensioning force is attained by synchronous loading of two jacks installed symmetrically relative to stud longitudinal axis in hollow of joint unit between its arc and washer surface preliminarily fitted on stud free end protruding beyond locknut. Tension force of flexible member is monitored by deformation of disk springs secured to end face of nut screwed on stud free end. Synchronous loading of jacks is continued until disk springs become fully spread, i.e., become flat. After this, locknut is tightened on stud. Force applied to flatten disk springs is selected from condition of its equalling the value of rated tensioning force of flexible member. EFFECT: higher mobility of support intended for use in conditions of side loads effect, and its design needs no foundation. 2 cl, 22 dwg
